Nat Turner

Nat Turner is Zach Weinberg’s Flatiron Health co-founder and a serial founder (Invite Health, Flatiron, then back into ops with Collectly and others). His angel pattern looks similar to Weinberg’s: digital health and tech-enabled care delivery, with an emphasis on companies that have to integrate with real clinical or operational workflows. AI focus not flagged. $100k-$250k checks at pre-seed through Series A, typically as part of a syndicate. New York-based, US scope. Best fit: founders with a clinical or operator background going after specialty care, oncology, RCM, or vertical workflow software for providers, anywhere Flatiron-style instincts about data, billing, and provider behavior are useful. Pure consumer wellness, biotech, devices, or platform-AI founders will struggle here. Entry path is LinkedIn or Twitter; warm intros from Flatiron alumni or current portfolio founders work best. He is straightforward and operator-minded, will dig into how you actually plan to deploy in clinics and what your path to a real ARR contract looks like. If you cannot answer those questions in detail, do the homework before reaching out; if you can, this is one of the higher-signal small checks in healthcare.
